Troy was a university student and the star quarterback of the University football team called the Grimsborough Quails. He was also the ex-boyfriend of Madison Springer, the head cheerleader of the Grimsborough Quails. The two had broken up after Madison found out that the victim was cheating on her. Troy had gray eyes, black hair and sported stubble. At the time of his death, Troy wore a blue American-Football kit, blue shorts and a blue helmet with the "Grimsborough Quails".

Murder details

Jones and the player attended one of the toughest games in the football season at the University Stadium, featuring the Grimsborough Quails (Jones' favourite team) versus their rivals, the Wippeka Armadillos. At one point of the match, Troy, the lead quarterback was running with the ball and suddenly collapsed onto the pitch. The fans and audience screamed and went wild. Also, Troy's right arm grew to an unnatural size and moments later, the stadium was evacuated, while the team rushed down to the field and received a confirmation that Troy was dead.

Nathan discovered that Troy had diabetes and was taking regular insulin. However, someone had got hold of the insulin and put Erythropoietin (EPO) in it. EPO was a form of steroids, designed to dope their player into remarkable agility and speed. But the EPO and the insulin were not allowed to mix, and it grew Troy's right arm into an immense and unnatural size. It also caused him to have a heart attack and that was what killed him.

Killer and motives

Troy was murdered by the Grimsborough Quails coach Franklin Caldwell.

Franklin was preparing his team for the upcoming match and discovered that there were talent scouts in the audience. Troy's skills were amazing, but his agility and speed needed improving. So Franklin sneaked into the infirmary where Troy's insulin was being distributed. He broke stole a bottle of EPO and mixed it with Troy's insulin, and then, distributed them to the victim, without knowing the effects. After Troy died and the team were getting closer to the truth, Franklin attempted to frame the nurse, Karimah Breen for the murder by placing the EPO in a fridge.

Since the motive contributed to reckless handling of students (although the sentence was mainly for Troy's death by unwillful EPO utilization, which caused the murder), Judge Hall sentenced Franklin to 4 years in jail and indefinitely cessates his teaching license.


  • Troy's name, 滝口 トロイ, with "滝口" meaning "Waterfall opening", and "トロイ" meaning "Troy".
